ATOMIZING DEVICE.

SPECIFICATION forming part of Letters Patent No. 738,848, dated September 15, 1903.

Application filed December 4, 1902. Serial No. 133.882. (No model.)

To all whom it may concern.-

Beit known that I, IVALTER SAMS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Atomizing Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to spraying apparatus, and particularly to perfumery bottles or receptacles employing the same, though I do not wish to be restricted to this particular adaptation of the invention.

As is well known to those familiar with perf umery-bottles that are equipped with spraying mechanism, there is employed a cylinder with a plunger therein and a containing vessel for the perfumery surrounding the cylinder and having communication with its interior, the lubrication of the working parts be ing effected by means of the perfumery finding its way to the interior of the cylinder. The objection to this class of apparatus will be readily understood, the perfuinery at best is a poor lubricant, and it contains reagents that are likely chemically to combine with the metal or other material within the cylinder to produce a substance as verdigris, that will tend to lock the piston in place. Considerable effort has frequently to be resorted to in order to free the piston after the bottle has been unused fora considerable length of time.

It is the object of my invention to provide a construction'whereby the use of the perfumery as a lubricant may not be required and whereby the perfumery is prevented from prises in its preferred embodiment a bottle or casing for the perfumery, within which there is projecting a cylinder that is desirably of such length as to project within the perfumery when any appreciable quantity there- There is arof is contained in the bottle.

bottle and at the same time to permit the airto be forced into the bottle, there is provided a connection between the interior of the cylinder and the interior of the bottle, through which connection or duct the air may be forced and which is so located with reference to the oil that the oil cannot be forced therethrough. I preferably so arrange this duct with reference to the cylinder that it will be immaterial in what position the bottle maybe, whether it is upside down, for the purpose of oilingi'he piston, or whether the bottle is upon its side, the oil will be prevented from passing through the duct. This result'is most desirably accomplished by shaping the duct in the form of a gooseneck, whose shorter end extends from the bottom of the cylinder and whose longer end extends well above the level of the perfumery. A stuffing-box surrounds that portion of the gooseneck passing through the bottom of the cylinder, so as to thoroughly seal this portion of the cylinder. The perfumery finds egress, preferably, at the upper portion of the bottle and with the aid of suction, there being provided at the exit'opening a spraying-nozzle into which an eduction-tube is led from the bottom of the bottle. The air finds direct passage through the nozzle, and as a consequence of the vacuum that tends to be formed at the nozzle in front of the educ- Lion-tube the perfumery is withdrawn.

I will explain my invention more fully by reference to the accompanying drawings, in which- Figure 1 is a vertical sectional view of a spraying or atomizing device constructed in accordance with my invention. Fig. 2 is a detail view of the gooseneck-duct, part being shown in section.

Fig. 3 is a side elevation of the eduction-tube wiih a spraying-nozzle in association therewith,portions of the structure being shown in section. Fig. 4 is a sectional plan view on line 4- 4 of Fig. 1.

Like parts are indicated bysimilar characters of reference throughout the different fig- The particular embodiment of the invention herewith shown is applied to a perfumery bottle or vessel a, in which is disposed the perfumery b in a liquid state. It is to be understood, however, that other liquids are adapted to be atomized by the device of the invention.

The eduction-tube 0 projects into the perfumery, the eduction-tube in this instance being curved to present a horizontal stretch of its bore to the nozzle-opening cl, that may be formed in a nozzle-plug e, that screws into an opening provided in the cap-section f of the bottle or casing, which section is preferably made of metal. This portion of the structure is well understood by those skilled in the art. The liquid 1) is forced through a duct or tube c by means of air that is under pressure within the bottle, the air finding passage through the annular space surrounding the eduction-tube and through the opening (1, causing the liquid 7' to be sucked through the tube 0.

The cap-section f is preferably removably secured in place, for which purpose it may have threaded engagement with a nether cap portion f, and in order that the joint between the cap portions may be most effectively sealed there is interposed between the same an annular packing-gasket f The cap f is provided with a cylindrical extension g, that constitutes the operating-cylinder of the apparatus. The plunger or piston his designed to work back and forth within the cylinder g, beingfor the purpose carried upon a piston-rod 'L, that terminates at its upper end in ,a button 70, designed to be engaged by the thumb or finger of the user, and which is adapted for free reciprocal movement within the bore of the cylinder. The coiled spring 70 is interposed between the bottom of the cylinder and the piston and tends to force the piston upwardly, which tendency is counteracted when the bottle is not in use by means of a head Z, that has threaded engagement with the cylinder 9 and is adapted for engagement with a cross-pin 0%, carried by the piston-rod i when this cross-pin does not register with a slot n, provided in the upper wall of the head 1-. When it is desired to use the bottle,the pin m is brought into the same plane with the slot at, so that the piston and pistonrod may be freely reciprocated.

The lower end of the cylinder 9 is closed by means of a stuffing-box that desirably comprises an inwardly-projecting cylindrical box portion 0 and gland 19, having threaded engagement with the interior of the said box portion, there being interposed between the top wall of the box portion 0 and a collar q, provided upon the air duct or pipe 7', a packing-ring s. The air-duct r is curved at its bottom, the shorter. end of the duct projecting within the cylinder 9, preferably through its bottom and above the level of the oil t in the cylinder. The longer end of the air-duct projects considerably above the liquid 1) and is provided at its end with a valve u, that will permit air to be forced into the bottle, yetit will prevent the return of this air, the air being limited to'the opening d in its egress.

The piston-rodz' may or may not be equipped with a valve, as desired. In some instances the piston, which is desirably formed of leather, may be adapted to also act as a valve,

while in other instances the addition of a special valve 1; of well-known construction the form of this element having the functions I have provided for it, as obviously the particular shape of this element is not an essential to its operativeness.

It is obvious that changes may readily be made in the embodiment of my invention that I have shown Without departing from the spirit of the invention, and I do not, therefore, wish to be limited to the precise construction shown; but,

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
